Use the following set of equations to solve questions (20 to 24) Based on Inverse method 2x1 - x2 = 4 3x1 + 2x2 = 2 (1) (2) The value of column 3 (C3) in the augmented matrix (A| 1) after zeroing element (a21) is: O [1/2, 1] O [1/2,-3/2] O [-1/2, -3/2]T None

The value of row 1 (R1) in the augmented matrix (AL 1) just after getting a unity diagonal is: O [1,0, 2/7, 1/7] O(1,0, -3/7, 2/7] O None [1,-1/2, 1/2,0]
